Patented Sept. 6, 1932 UNITED STATES PATENT OFFICE HOWARD B. HASKINS, OF HIGHLAND PARK, MICHIGAN, ASSIGNOR TO TERNSTEDT MANUFACTURING COMPANY, OF DETROIT, MICHIGAN, A CORPORATION. OF MIGH- IGAN DOVETAIL Application filed December 21, 1981.

This invention relates to a dovetail for an automotive vehicle body. This invention more particularly relates to an improvement in a type of dovetail such as shown in the co-pending application of Howard B. Haskins and Emory Glenn Simpson, Serial No. 549,448, filed July 8, 1931. The type of dovetail shown in the above co-pending application has proved highly satisfactory both as a registering device for properly aligning the door in the door opening, and as a bumper for throwing the door open when the latch bolt is retracted. In this form the dovetail cushions the door and functions silently in its in and out movement and in its upward and downward movement as it adj usts itself to the relative movement between the door and the door opening, .but it has been found that the relative edgewise movement between the door and the door opening causes a rattle between the dovetail socket and its casing. This rattle arises by virtue of the'commercial tolerances permitted between the side faces of the dovetail socket and its casing. Hence, it is an object of this invention to eliminate this rattle.

In the drawing:

Fig. l is a fragmentary detail of the door and body pillars of a vehicle body showing the dovetail in position.

Fig. 2 is a section along the line 2-2 of Figure 1.

Figs. 3 and 4 are details of the dovetail shoe showing the anti-rattler inserts.

Fig. 5 is a detail of a modified form of dovetail shoe showing a different type of insert.

Fig. 6 is a section along the line 6-6 of Figure 5.

In the drawing the vehicle body pillar 1 is provided with a recess 2 which receives the dovetailcasihg 3, provided'with the cover plate 4. The casing 3 is adapted toreceive the female member 5 which has a dovetail socket 6 for the reception of the wedge mem: ber 7 which is carried by the door pillar 8. The socket member 5, as described in the above mentioned co-pending. application, is cushioned above and below by the rubber blocks 10, and is spring .loaded by the coil Serial No. 582,237.

springs 11 which are mounted between the back of the casing 3, and which engage the socket member 5 in the openings 12.

In fabricating this type of dovetail, it is commercially impractical to obtain a nice rattle or noise proof fit between the side face of the socket member}; and the front plate 4, and the side face of the socket member and the back of the casing 3, consequently, when the wedge member 7 interengages the member 5 in the socket 6, the body weaves and other movements incident to the operation of an automotive vehicle, will cause relative movement in an edgewise direction between the door 8 and the door opening. This movement will be transmitted through the wedge member 7 to the socket 5, thereby causing the socket 5 to move sidewise, or to the left and to the right as viewed in Figure 2. This sidewise movement, owing to the clearance 13, i. e., commercial clearance and tolerance, between the female member -5 and the front plate 4 and the back 20 of the casing 3, will set up a rattle or noise unless the clearance is taken up. .To prevent a this rattle or noise it is proposed to mount suitable anti-rattling inserts between both the back 20 and the front plate 4 of the casing and the shoe 5.

To-this end the socket member 5 is provided with a plurality of recesses 14 on the side faces which are each adapted to receive a suitable insert 15. As shown the side face of the socket -member 5 is provided with a pair of inserts 15, one on either side of the socket 6, and the side face is provided with three inserts as shown in Figure 4. These inserts may be of any suitable resilient or sound deadening material such as felt, cork, or rubber.

As shown in Figures 1 to 4, the inserts are felt and preferably soaked in oil prior to their insertion in the recesses 14. .It will be noted, particularly in Figure2, that the inserts 15'project outwardly from the side faces of the socket member 5 into engagement with the front plate 4 and the back 20 of the cas- 'ing 3, thus to effectively eliminate relative V In Figures 5 and 6 there is shown a modified form of dovetail socket and insert. In this form the socket member 50 is provided with suitable recesses 16 for reception of the headed rubber buttons 17. These rubber buttons 17 are preferably of molded rubber, sufficiently hard so that they will permit relative sliding movement between the socket member 50 and the casing 3, and yet effectively cushion the side faces of the socket 50 against clashing with the front and back of the casing I claim:
